I think that, overall, world hunger is best met by focusing on
plant-based diets. However, in terms of feeding humans, there may be a place for
animal agriculture.

I stress that many "uses" of animals may cause animal
suffering, which raises important ethical issues. But, if we restrict our
attention to the issue of feeding people, I don't see things as black-and-white.

There are places where grasses grow upon which animals may
feed, but the ground is not useful for agriculture due to insufficient rain,
poor quality soil, uneven and/or rocky terrain, or other reasons. Animal foods
can provide much-needed protein, and animals can be used to help till soils to
grow food, including vegetables.

I'm not endorsing HPI (and I don't approve of images that
suggest that the relationship between the people and animals is loving and
compassionate, because often it isn't), but I think that animal agriculture may
help alleviate hunger in certain circumstances.
